My invention relates. to sav ings clocks of that type in which the inserted coin is intercepted by two members" which project in a lateral recess of thecoin channel and-which allow the coin to slide down slowly wherein thelattenso long it remains in the channel,

holds a lever acting uponthe locking'inechanismoji the clock movement in the releasing position and,, as soon as it falls out allows thislever to enter the locking positiomif a second coin benot inserted. In known'c'lock of this type one-ofthe said two members is fcrmedby. aslowly rotating disc having angular recesses and arms fermedthereby and the other member is formed by a siring operated lever whichis at first held one of the arms-on said discinposition to intercept a coin in the coin channel, but after said disc has rotated a certain distance is moved by its spring into one of the recesses on said disc I to permit the cointo be released and to be interceptedby one ofthelarms on said disc, and on further rotation .ot'said discis movedhaek by the next succeeding arm into intercepting position. U I r v New, accordingto my inve ntion,}the said two interceptingmembers are both formed by spring operatedlevers which proje'cta certain distance one above the other into said lateral recess of the coinchannel and arealternatively moved into intercepting position. by two toothed discs rotating with each other and displaced to -arch other at a certain angle. In this construction the first intercepting lcver (as wcll as the second) has already finished itsmovement into interceptingposition when thecoin strikes upon it, whilst'in the known }construction the lever-is obliged to somewhat, wherein iteasily happens that the latter becomes clamped. Y

In the accompanying drawings 1,

shows the mechanism of a savings clockconstructed according-to my invention with the locking lever in the releasing position in front view, Fig. 2- shows the coin channel with the intercepting device in side view Fig, 3 shows a part of the coin channel with the intercepting device in another position of the latter in front View, and Fig. 4 shows parts of the coin channel and of the locking lever in back view.

To the front wall of the coin channel 1 there is fixed a plate 2 on which is pivotally mounted at 3 the locking lever 4, 5. The rearwardly bent part 6 of the lever arm 4' l'pitch of the ratchet gearing.

projects into four lateral recesses 7 disposed one above aiiothenin the twowalls o't ,the

channel '1 and is provided withthree pairs of slots, through which project thethree pairs,

of tongues 8 separating the recesses 7 from each other The laterally projecting part 9 oi"? the lever arm acts upon thelocking. d e- I vice oi": the clock movement. This device is under the action of a spring 13 such a position 7 that the hook 12 projects into'the' path of a pin 15 fixed to the cloclcbalance 14g and thus .tormedhywan oscillating member 11 having a (i5 stops the latter together witlithe-clocl; movc tween the lever part 6 and-the oppositely. disposed edge otthe channel'l and thereby brings the lever l, 5 intothe releasing position, indicated in the drawing,- in which the certain space of time consists of two levers-17 and :18, which are mounted on the plate 2 at 19 one behind another and movable inde- ,ment. If a. coin 16 be inserted it slips be-- pendently of eachotherj and o'l two equal ratchet discs 20. and 21, which aresecuredto l .atooth ed ,wheel 22 a certain distance one be hind another and displaced to each other at an angle corresponding to half the circular The Wheel 22 is rotated slowly bya pinion :23 of the clock movement in the direction indicated by the move somewhat further and and the coin arrow. A spring 24 attached to alaterally a spring 26 attachedto a laterally projecting lug of the lever 18 continuouslypresses the latter with its forwardly hentlug 27 uponthe periphery of the disc 21:

When the partsare in the positioii'iridi cated'in Fig. 1, the h1g2?) of the lever 17 rests ill on atooth of the disc and the laterally bent 1 end 28 of this lever projects into a lateral recess 29 of the channel 1 to such an extent, that it intercepts the firstly inserted coin 16,.Whilst thelug 27 of the lever 18 rests in a toothgap of the disc 21 and the rearwardly bent end 30 of this lever-projects a little only into the the lever 17 falls under the action'of the spring 24 with its lug 25 into the next succeeding tooth-gap of the disc 20, wherein the coin 16 falls down from the end 28 and is intercepted by the end 30; see Fig. 3. In further rotation of the discs 20 and 21 vice versa the lug 25 of the lever 17 rises on the next succeeding tooth of the disc 20, whereby this lever is moved in such manner that its end 28 projects into the recess 29 to a greater extent again, whilst after the discs have again rotated through an angle corresponding to half the pitch, the lever 18 falls under the action of the spring 26 with its lug 27 into the next succeeding tooth-gap of the disc 21,

wherein the coin 16 falls down from the end 30 and out of the channell and the second coin 31 is intercepted by the end 28. The parts are then again in the position indicated in Fig. 1. If there be no second coin in the channel 1, the locking lever 4, 5 swings back, as the first coin 16 falls out, and with it also the oscillating member 11, so that the hook 12 again stops the balance '14 together withthe clock movement.

Whilst in known savings clocks a suitable channel for each set of coins of different size is needed and the locking lever as wellas the intercepting device need to be adjusted to the respective coin size, in the present construction a single channel sufiices for all coin sizes within certain limits, and in every case the locking lever only needs to be adjusted to the respective coin size, which is easily and readily pert'ormable. For this purpose the arm 4 of the locking lever is secured to the arm 5 by means of screws 32 which pass through parallel transverse slots 33 of the arm 4 into the arm 5 so that the former is adjustable transversely to the channel 1, and on the plate 2 there is provided an adjustable stop piece for the locking lever. This stop piece is formed by a lever 34, which, after the arm 1 has been adjusted to the diameter of the respective coin by means of a rule 35 (Fig. 4),

the width of which is equal to this diameter, is locked by means of a screw 36 (Fig. I) in such manner that its lower end lies close to the part 6 of the arm4 and thus limits the move ment of the lever 4, 5 in the releasing position. As the recess of the channel 1 for the part 6 of the arm 4 is divided by the tongues 6 into smaller parts 7, the coins are prevented from falling out through this recess.

What I claim as my invention and desire to secure by Letters Patent is:

1. In a savings clock, a coin channel, means for engaging the clock movement to prevent the clock from running, means actuated by the weight of a coin for moving said first mentioned means to permit the clock to run, two spring operated members for intercept ing a coin in said channel, said members projecting a certain distance one above another into a lateral recess of said channel, and means actuated by the clock movement for moving said members into intercepting position alternatively.

2. In a savings clock, a coinchannel, means for engaging the clock movement to prevent the clocli from running, meansactuated by the weight of a coin for moving said first mentioned means to permit the clock to run, two spring operated levers for intercepting a coin in said channel, said levers projecting a certain distance one above another into a lateral recess of said channel, and two toothed discs for moving said levers into intercepting position alternatively, said discs slowly rotating with each other and being displaced to each other at a certain angle.

3. In a savings clock, a coin channel, means for engaging the clock movement to prevent the clock from running, a lever actuated by the weight of a coin for moving said means to permit the clock to run, said lever having an arm which projects into a lateral recess of said channel and is secured to said lever so as to be adjustable transversely to said channel, and an adjustable stop for said lever arm.

4. In a savings clock, a coin channel, means for engaging the clock movement to prevent the clock from running, and a lever actuated by the weight of a coin for moving'said means to permit the clock to run, said lever having an arm which projects into a lateral recess of of said channel and is secured tosaid lever so as to he adjustable transversely to'said channel, said recess being divided b tongues project-ing through slots provide in said levera-r 1 In testimony whereof I afiix my signature.
